PORT ST. LUCIE — The 70-win Mets have come to this camp with an attitude. Jose Reyes showed yesterday that he has David Wright’s back.

Shortly after Wright told reporters in the dugout that he expected the 2010 Mets to win the World Series, Reyes said over in the minor league clubhouse that there is “no doubt” the Mets can make it to the World Series and win it all.

The initial reaction here is to say that Wright and Reyes are delusional. What’s next, manager Jerry Manuel changing his uniform to No. 3?

But Wright and Reyes make up the core of these Mets. They are the ones who should be talking. They are the ones who should be making these kinds of proclamations. They are the ones who are supposed to be the voice of this franchise.

There’s nothing wrong in believing in your team, especially when no one else believes in it. And no one believes in the Mets right now. It has to start somewhere.

A healthy Reyes said he believes he can make a difference and is shooting to have a big season. He said he is looking to bat over .300, have at least “200 hits” and hopes to steal 50 bases.

“If I feel good, it’s going to have to be at least 50 bases,” he said with his trademark smile.

This is a huge season for Reyes in so many ways.

The Mets have an $11 million option on his 2011 contract. He needs to produce. Reyes said he wants to remain a Met his entire career.

Reyes said he thinks if he stays healthy, the marriage will continue for many years.

“Right now, I’m not thinking about contract stuff,” Reyes said. “I just want to get on the field and try to do my job and put up good numbers and try to help this team win. That’s my goal right now.”

Reyes said he believes that if the Mets are healthy, the wins will take care of themselves.

The most important factor to consider here is that Reyes is talking about big numbers because he feels healthy. Unhealthy players do not make big, bold predictions.

Reyes said he feels he is healed completely following his hamstring tendon surgery.

“Last year was horrible, people don’t know what I’ve been through,” Reyes said. “I came down here like four times [on rehab assignments]. I’m here like two days and I have a setback and I have to go back to New York again to see the doctors. Then they send me back here again. One day I’m excited, the next day I’m hurting. It drove me crazy. I didn’t see any good results.”

Reyes is convinced those days are behind him and said he thinks there is enough talent in the room for the Mets to succeed. He points to the Mets of 2006 and yes, the collapses of ’07 and ’08. He said the only difference talent-wise between those teams and this team is “that [Carlos] Delgado is not here.”

“But we have Jason Bay now,” Reyes added. “We still have real good players here. The key is we have to be healthy.”

There was a scene yesterday on the field that meant so much to Reyes.

“David said to me, ‘Man, I’m glad you’re back,’ ” Reyes said. “David was happy. I’m happy too to be back. We always joke around together on the field.”

They were once the bright lights of the Mets’ future. Now Wright and Reyes have to prove they are the present and future.

“It was a tough year for David,” Reyes said. “To have me, [Carlos] Beltran, Delgado, all out at the same time. It was hard for him.”

Wright and Reyes believe, and they are not afraid to say it. But it’s time for them to produce and lead the way. That’s the only way they will have something to talk about.
